Mini in NHTSA’s records
Where the codes point: NHTSA lists Mini-related WMI codes for Mexico (1) and United States (1). The first character of a VIN usually reflects the country where the vehicle was built, so two cars of the same Mini model can start with different characters if they were built in different plants.

Reading a Mini VIN
A Mini VIN follows the same federal 17-character format as every vehicle sold in the US since the 1981 model year. The first three characters are the World Manufacturer Identifier (3T1, 421 for Mini), positions 4–8 are Mini's own codes for the model line, body, engine and restraints, position 9 is the check digit, position 10 is the model year and position 11 is the assembly plant.
Because positions 4–8 are maker-specific, the decoder above asks NHTSA's vPIC catalog to translate them, then matches the year, make and model to Mini's recall campaigns and owner complaints. For a position-by-position walkthrough see how to read a VIN; for the year letter, use the model-year code chart.
Mini VIN decoder FAQ
Where is the VIN on a Mini?
On a Mini car, SUV or light truck, look through the windshield at the driver's-side corner of the dashboard, or read the label on the driver's door jamb. It is also on the title, registration and insurance card. Our guide shows where to find the VIN on each body type.
How do I find the model year from a Mini VIN?
Look at the 10th character. For cars, SUVs and light trucks, a letter in position 7 means the 2010–2039 cycle and a number means 1980–2009, so the same letter can point to two years 30 years apart.
Does a Mini VIN decoder show recalls?
It shows the recall campaigns NHTSA lists for that Mini model year (40 campaigns across the Mini models in our data). Whether your specific vehicle still needs a repair is only shown by NHTSA's VIN lookup or a Mini dealer.
What do the first three characters of a Mini VIN mean?
They are the World Manufacturer Identifier. NHTSA has 2 WMI codes on file for manufacturers matching Mini, including 3T1, 421. The full list is in the table above.
Which Mini models have the most complaints filed with NHTSA?
In our data: Cooper (2,421), Cooper S (1,920), Clubman (286). Counts are owner reports across all model years, not failure rates; popular models draw more reports.

- Recalls and complaints are matched by the decoded year, make and model, not by your VIN.
Limitations
- Complaint counts are owner reports, not verified findings or failure rates. There is no sales denominator.
- Recall campaigns are listed for the model year. Only NHTSA and the automaker know whether a specific car was repaired.
- Recent model years are still collecting reports.
